Villain is unknown reg. Since i don't have bdfd my plan was to xc once and xf almost on all turns. But i hit my straight and my question about sizing of xR. Did i pick good sizing or need to make it slighly lesser/bigger? On turn he reraised me and left only a few bbs in his stack. I didn't see fold there. I had second nuts + i block first nuts, he could have same hand as mine, sets, combo draw. Are there any other lines? How would you play this hand?

its fine i think

I think, that if you think he can have 65s then you also have to assume he opens 22-44 from UTG. If so then it's a clear call as he has way more sets than straights. Add to that some overplayed big pairs and maybe Ax and you're way ahead.

That said I think the flop call is a tad loose with only a gutshot and no back door flush draw.

you can x/r that flop a lot, utg likely cb too much
